Then, the aspects and the criteria of each of them are extracted. Then, for the productivity issue, 20 indices and for the financial and economic benefits, 16 indices were extracted from papers and researches. This study has been conducted through two research methods: exploratory and descriptive. In the descriptive portion, the indices and the concepts effecting on the issues of productivity, and financial and economic benefits were extracted separately. In the exploratory method, the relationships among the defined concepts and indices in the two fields of productivity, and financial and economic benefits, which have been acquired from the literature, have been specified. Regarding the introduced issues for finding a meaningful relationship between productivity, and financial and economic benefits, a questionnaire was developed which was filled in by the experts in the industry and university sectors. In the first set, the questionnaire was designed for finding a significant relationship between financial and economic benefits, and productivity. The related indices were extracted by means of t-test with significant level of 5 percent. Among the related indices, the ones with strongest relationships were determined and reported. In the second set of questionnaires, the relationships between indicators and variables were recorded, and the work was done by calculating the Pearson correlation coefficient. The data was analyzed by Minitab software.

The difference between the present study and the previous ones, is that the deterioration of product continues during the traveling time, which depends on the carrier’s mode to ship batches from vendor to buyer. So the structure of existing models changes. The purpose of this study, is to minimize the total cost of buyer and vendor, and to obtain the number of shipments, the vendor’s production cycle time, and the carrier’s type. We propose an algorithm to solve the independent model of buyer and vendor with the affirmation of cost functions’ convexity, and a heuristic algorithm to solve the integrated model.

Determining the optimal inventory control policy for remanufactured products, that is considered in the closed loop supply chain, is one of the important problems in the supply chain management of deteriorating items (in closed loop supply chain, the customer is able to return the used products to the reverse flow for remanufacturing or reusing). In this paper, we analyze an inventory system for closed-loop supply chain with multi-manufacturing and multi-remanufacturing cycles under stochastic demands. The manufacturing cycle is used for direct flow of supply chain; while the remanufacturing cycle is applied for reverse flow, in which the used products return to the production system. The supply chain is for echelons including retailer, manufacturer, collector, and material supplier in which shortage is allowed and completely backlogged. The decision is made initially by the down-stream player (from retailer to supplier). We generalize three different cases: 1. Single manufacturing cycle and single remanufacturing cycle, 2. Single manufacturing cycle and multi-remanufacturing cycles, and 3. Multi-manufacturing cycles and single remanufacturing cycle. Moreover, a heuristic algorithm is presented to obtain the optimal solution.
